Natural Resources and Their Use

Chapter 1 · Social Science · Class 8 24 min read

Why This Matters

Take a pause. Look at yourself, and at the things around you right now.

Your shirt. The chair you are sitting on. The pencil in your hand. Even the plastic button on your shirt. Where did each one come from?

Trace each thing back, step by step, and you reach the same answer every time: Nature. The cotton in your shirt grew in a field. The wood in your chair came from a tree. The plastic button was made from petroleum, which lay deep underground. Everything we use begins in Nature.

This is a huge idea. We do not “make” things out of nothing. We take materials from Nature and shape them. The air we breathe, the water we drink, the food we eat, the metal in our phones, the coal that makes much of our electricity — all of it is borrowed from the Earth.

But here is the worrying part. Some of these gifts can refill themselves. Others cannot. If we use them carelessly, they run out. And when a resource runs out, it does not come back in our lifetime — sometimes not for millions of years.

So this chapter answers three big questions. What exactly is a “natural resource”? How do we sort them into useful groups? And why must we use them with care, so that we — and the people who come after us — never run short?

The Big Idea

A natural resource is anything in Nature that is useful to humans — air, water, soil, forests, minerals, fuels, sunlight, wind. But a part of Nature only becomes a “resource” when we can actually use it: we must be able to reach it, afford it, and be allowed to use it. We sort resources in helpful ways — by their use (essential for life, for materials, for energy) and by whether they refill themselves. Renewable resources, like forests and river water, refill in our lifetime if we do not over-use them. Non-renewable resources, like coal and metals, took millions of years to form and cannot be replaced once used up. The most important lesson is this: Nature works in cycles where nothing is wasted, and renews herself — but only if we do not take faster than she can give back. Using resources wisely, so they last for us and for future generations, is called stewardship.

Let’s Break It Down

When does Nature become a resource?

The word Nature means all the life and non-life things in our environment that humans did not create. Trees, rivers, rocks, air, sunlight — Nature made all of these, not us.

So when does a piece of Nature become a resource? The answer is: when humans use it. A tree standing in a forest is just part of Nature. The moment we cut it and turn its wood into a chair, we treat that tree as a resource.

But there is a catch. Not everything in Nature can be used easily. Think about petroleum lying deep under the ocean floor. It is there, but if we have no technology to reach it, it is not a resource to us yet. Or think of a sacred grove — a small forest that a community treats as holy. We could cut those trees, but it would be wrong, so we do not.

So for something to count as a resource, it must pass three tests. The diagram below shows them clearly. Look at it first, then read on.

A flow showing when Nature becomes a resource. A tree in the forest is part of Nature. To become a resource, it must pass three tests: technologically accessible, economically feasible, and culturally acceptable. If it passes all three, it becomes a resource, such as wood made into furniture.
Figure 1.1 — When a part of Nature becomes a resource. On the left, a tree in the forest is simply part of Nature. The blue arrow leads to three tests it must pass. Test 1, technologically accessible, means we have the tools to reach and extract it. Test 2, economically feasible, means getting it is worth the cost. Test 3, culturally acceptable, means society allows it, so a sacred grove stays off-limits. Only if it passes all three (red box at the bottom) does it become a usable resource, like wood turned into furniture. The blue side-note reminds us that if it fails even one test, it stays part of Nature, not yet a resource.

Here is the simplest way to remember it. A part of Nature is only a resource when we can reach it, afford it, and are allowed to use it. (One small note about a word you will see: exploitation. In everyday talk it sounds bad. But in this chapter it simply means “extracting and using a natural resource”. It does not always mean something harmful.)

So, in short: natural resources are the materials and substances that occur in Nature and are valuable to humans.

Sorting resources by their use

In science you learned that we group things to understand them better. When we give a group one short name, like “living things” or “non-living things”, everyone instantly knows what we mean. We do not have to describe it every time. Grouping makes thinking and talking easier.

We do the same with natural resources. There are many ways to sort them. One useful way is to ask: what do we use this resource for? This gives us three groups. The classification tree below lays them out.

A classification tree. Natural resources split into three groups by use: resources essential for life such as air, water and food; resources for materials such as wood, marble, coal and gold; and resources for energy such as coal, petroleum, natural gas, sunlight and wind.
Figure 1.2 — Sorting natural resources by how we use them. The dark box at the top is the whole set of natural resources. It branches into three groups. The green branch, essential for life, holds the things we cannot live without: the air we breathe, the water we drink, and food from the soil. The blue branch, for materials, holds what we shape into useful or beautiful objects: wood, marble, coal, gold, metal ores and stone. The yellow branch, for energy, holds what powers our modern life: coal, petroleum, natural gas, water, sunlight and wind. The note at the bottom points out that one resource can sit in two groups, because coal is both a material and an energy source.

Let us look at each group, and why it matters.

Resources essential for life. Life on Earth could not exist without the air we breathe, the water we drink and the food we eat. We take air from the atmosphere, water from rivers and ponds, and food from soil and from other living things. Here is the key point: we cannot make these ourselves. No factory makes breathable air or drinkable water from nothing. That is exactly why they are so precious — there is no backup if we ruin them.

Resources for materials. Humans love to make things — both useful things and beautiful things. A single piece of wood can become a sturdy chair or a carved statue. India’s land is so varied that it gives us a huge range of materials, from wood to marble, and coal to gold. These let us build homes, tools, machines and art.

Resources for energy. Modern life runs on energy. Electricity lights our homes, runs our trains, and powers every factory. That energy comes from natural sources: coal, water, petroleum, natural gas, sunlight, wind, and more. Without energy resources, almost nothing in a modern country would work.

Notice one clever thing. The same resource can belong to more than one group. Coal is a material (we can make things with it) and also an energy source (we burn it for electricity). That is fine. We are sorting by use, so one resource can appear in two branches.

Renewable and non-renewable resources

There is a second, very important way to sort resources. We ask: can Nature refill this resource, or not? This splits them into renewable and non-renewable.

To understand this, we first need to see how Nature works. Nature has a wonderful habit: she heals and renews herself. A cut on your skin closes up on its own. A forest grows back after a wildfire. This healing is called restoration — returning something to its healthy state. Nature goes even further with regeneration — creating brand new life. Plant the right trees where a forest was cut, and birds, squirrels and insects return; life comes back.

The best example is a forest cycle, where there is no waste at all. Follow the cycle in the diagram below.

A circular diagram of Nature's no-waste cycle in a forest. A tree grows, then falls, then decomposers like bacteria, fungi and insects break it down, then the soil becomes rich, then new seeds sprout, and the cycle returns to a tree growing.
Figure 1.3 — Nature's cycle in a forest, where nothing is wasted. The centre circle reminds us that a forest renews itself. Going clockwise: (1) a tree grows tall and healthy; (2) after many years it falls; (3) decomposers, the bacteria, fungi and insects, break the fallen tree down; (4) the broken-down tree becomes part of the soil and makes it rich; (5) seeds sprout in that rich soil and new plants begin, which leads back to step 1. The green arrows show the loop closing. The note below explains the magic: every output becomes the next step's input, which is why a healthy forest never runs out.

This idea of a cycle with no waste is the heart of the chapter. Now we can define our two types.

Renewable resources follow this restoring-and-regenerating pattern. Most of India gets plenty of sunshine. Rivers are fed again and again by rain and melting glaciers. Forests grow back. Soil replenishes itself. So solar energy, wind energy, energy from flowing water, and timber from forests are renewableas long as we manage them carefully.

But here is the condition you must never forget. A renewable resource stays renewable only if we do not disturb Nature’s rhythm. If we cut timber faster than the forest can grow new trees, the forest will shrink and finally disappear. The “refill” cannot keep up. So even a renewable resource can be destroyed by greed.

Non-renewable resources are different. They form over enormously long periods — millions of years — and cannot be replaced at the speed we use them. Fossil fuels like coal and petroleum, and metals like iron, copper and gold, are non-renewable. India has large coal reserves, and we mine coal for energy. But it has been estimated that India’s coal may last only about another 50 years, while our demand for electricity keeps rising. Once it is gone, there is no quick way to make more.

The comparison below puts the two side by side so you can see the difference at a glance.

A side-by-side comparison. Renewable resources, shown with a green refresh-cycle arrow, refill in nature within a human lifetime and include sunlight, wind, flowing water, forests and soil. Non-renewable resources, shown with an hourglass, took millions of years to form and run out, and include coal, petroleum, iron, copper and gold.
Figure 1.4 — Renewable versus non-renewable resources, side by side. On the green left side, the circular refresh arrow shows that renewable resources refill in our lifetime, if we do not over-use them; examples are sunlight, wind, flowing water, forests and soil, which refill within years or decades. On the red right side, the hourglass shows that non-renewable resources took millions of years to form and are gone once used up; examples are coal, petroleum, natural gas, iron, copper and gold, and India's coal may last only about 50 years. The key difference is the speed of refilling: fast for renewables, far too slow for non-renewables.

Why does this difference matter so much? Because it tells us how to use each one. A renewable resource we can use forever — but only at a gentle pace that lets it refill. A non-renewable resource we must use sparingly, stretching it out until we find better alternatives.

Before we go on, let us refresh one idea from science that we just used.

Now check whether you have understood the “why” behind renewable resources.

Concept check

Sunlight and a forest are both called renewable. But a forest can still be destroyed by humans, while sunlight cannot. Why is that?

Why over-use turns a renewable resource into a problem

We just said a renewable resource can be ruined if we take it too fast. Let us see exactly why, because this is the single most important idea for the rest of the chapter.

Think of a renewable resource like a water tank. Nature pours water in (the refill), and we draw water out (our use). As long as the inflow keeps up with the outflow, the tank stays full forever. But if we open our tap much wider than Nature’s, the tank empties — a little more each day — until it runs dry. The picture below shows both cases.

A balance comparison of two tanks. On the left, the rate we take water equals the rate Nature refills it, so the tank stays full and the resource lasts forever. On the right, we take much faster than Nature refills, so the tank empties and the resource runs out, like Punjab's groundwater.
Figure 1.5 — Why the rate of use decides everything, shown as two water tanks. In panel (a) on the green left, Nature's refill arrow and our take arrow are the same size, so the tank stays full and the resource lasts forever; this is true renewable use. In panel (b) on the red right, the refill arrow is thin and slow while our take arrow is thick and fast, so the water level drops, the tank runs low, and the deficit builds up each year until it runs out. The real-life example given is Punjab's groundwater, which has been drawn far faster than rain can refill it.

Now look at two real examples from India where exactly this is happening.

Groundwater. Many farmers pump water from under the ground to water their crops. In most states, they pump it out faster than rain can soak back down and refill it. So the underground “tank” keeps dropping. Over time it gets deeper and costlier to reach the water, and finally it can run out. Experts warn that several of our growing cities may run short of groundwater soon.

Soil. Soil is renewable too, but it can be degraded. When farmers use too many chemical fertilisers and pesticides, the soil loses its health. Traditional farming treated soil as part of Mother Earth, using cow dung, mulching (covering soil with leaves and straw), and growing many crops together. These methods kept the soil alive and rich. Used carelessly, chemicals strip the soil of that life.

There is also a special danger. Industries make the goods we need, but they often dump waste into rivers. Some of that waste cannot decompose — decomposers cannot eat it. So instead of joining Nature’s cycle, it poisons the river until the water can no longer support life. That breaks the no-waste cycle we admired earlier.

Uneven distribution and its effects

Here is another fact about resources: they are not spread evenly across the world, or even across one country. Some places are rich in coal, others in oil, others have almost no minerals at all.

This uneven spread has big effects on human life. It shapes where people settle, what they trade, and how countries get along. When an industry is set up near a resource, a town grows around it. Jobs appear. Schools, hospitals and roads follow. So resources can bring prosperity.

But there are costs too. People living on resource-rich land are sometimes forced to leave their homes so the resource can be mined. Sometimes their sacred places are threatened, which leads to conflict.

And because Nature ignores our political borders, resources often have to be shared across states and countries — which is not easy. A river, for example, flows through many regions, and each one wants its share of the water. India’s Kaveri river is shared by Karnataka, Tamil Nadu, Kerala and Puducherry. Keeping the sharing fair and peaceful took long, careful negotiation. Across the world, many wars have been fought just to control natural resources.

There is also a surprising twist called the natural resource curse (or the “paradox of plenty”). It sounds odd, but having lots of natural resources does not automatically make a country rich. Why not? Because if a region only digs up and sells the raw resource — without building industries to turn it into more valuable products — it stays poor. India has mostly avoided this curse by investing in technology and skills to process its resources. Simply having resources is not enough; knowledge, good governance and planning decide whether they become lasting wealth.

Concept check

Two countries each have huge reserves of iron ore. One becomes wealthy from it and the other stays poor. Using the idea of the resource curse, suggest why.

Using resources wisely: stewardship

So what should we actually do? The answer is stewardship — caring for natural resources responsibly, the way a good guardian cares for something precious. Stewardship has two simple rules, one for each type of resource. The flow below shows them.

A flow showing stewardship, the wise use of resources. The goal is to sustain life on Earth. It splits into two paths: for renewable resources, restore and regenerate through water harvesting, organic farming and planting native trees; for non-renewable resources, use them judiciously and switch to renewable alternatives like solar power. Both paths lead to lasting benefits for present and future generations.
Figure 1.6 — Stewardship: the two rules for using resources wisely. The dark box at the top states the goal, to sustain life on Earth by respecting Nature and wasting nothing. It splits into two paths. On the green left, if a resource is renewable, we restore and regenerate it, by harvesting rainwater and reviving ponds, organic farming like the Sikkim model, planting native trees, and pausing fishing during the breeding season, all so we use it no faster than it refills. On the yellow right, if a resource is non-renewable, we use it judiciously and find substitutes, by wasting less coal, switching to solar and wind energy, using greener cement and recycled materials, and joining efforts like the International Solar Alliance. Both paths meet at the bottom in lasting benefits for us and for future generations.

Let us see real Indian examples of each rule in action.

Restoring renewable resources. To fix falling groundwater, India is reviving old water-harvesting methods — catching rainwater, rejuvenating ponds and tanks, cutting wasteful water use, and reusing water. To heal soil, farmers are returning to natural methods. The state of Sikkim is a shining example. Pema’s family there switched from costly chemicals to compost and natural pest repellents made from neem and garlic, and grew many crops together. The yields dropped at first while the soil recovered, but after about five years the farm thrived. In 2016 Sikkim became a 100% organic state — birds and helpful insects returned, tourism rose, and farmers’ incomes grew by about 20%. It now shows the whole world that a region can farm sustainably and prosper.

Using non-renewable resources judiciously. For resources that cannot refill, the rule is to stretch them out and find substitutes. The biggest move is switching to renewable energy. India and France launched the International Solar Alliance in 2015 — a group of sunny countries working together on solar power. The huge Bhadla Solar Park in Rajasthan shows how a country can shift from fossil fuels to clean sunlight. India has also helped fund solar projects in many developing nations.

Even the materials we build with can be made greener. Cement is one of the most polluting industries — its dust harms our lungs, settles on plant leaves, and pollutes soil and water. So India is reviving traditional, low-pollution materials like stone and mud. The Jaisalmer fort in Rajasthan, built centuries ago, is largely a mud structure. Modern mud buildings in Auroville prove these old methods still work beautifully today.

There is one more idea we must hold on to: fairness. Even basic resources like clean water and clean air do not reach everyone equally. In many cities, some areas get no regular drinking water, and air pollution hits hardest those who cannot protect themselves. True stewardship means caring for all people, not just ourselves. The Bhagavad Gita calls this lokasangraha — the idea that we should rise above our own desires and act for the wellbeing of everyone.

Common Mistakes

Here are three slip-ups students often make. Read them once, and you will not be caught out.

⚠️ Common mistake
What students think

Renewable resources can never run out, so we can use them as much as we like.

Why it seems right

The word 'renewable' sounds like a promise that the resource keeps coming back no matter what, so it feels safe to use it freely.

What actually happens

Renewable means a resource can refill itself, but only at its own natural speed. If we use it faster than it refills, like cutting a forest faster than trees grow, or pumping groundwater faster than rain replaces it, it shrinks and can run out. Renewable does not mean unlimited.

⚠️ Common mistake
What students think

Anything found in Nature is automatically a natural resource.

Why it seems right

Everything we use does come from Nature, so it seems natural to assume that every part of Nature counts as a resource straight away.

What actually happens

A part of Nature becomes a resource only when we can actually use it. It must pass three tests: we must be able to reach it with technology, afford to extract it, and be allowed to use it. Petroleum we cannot reach, or trees in a sacred grove, are part of Nature but not yet usable resources.

⚠️ Common mistake
What students think

A country with lots of natural resources is sure to be rich.

Why it seems right

It feels obvious that more resources should mean more wealth, the way more money in your pocket means you can buy more.

What actually happens

This is the natural resource curse, or paradox of plenty. Resources alone do not create wealth. A region grows rich only if it builds industries, with the right technology and skills, to turn raw resources into higher-value products. Without that, it may just sell raw materials cheaply and stay poor.

Summary

Here is everything you can now explain to a friend:

  • A natural resource is any material or substance in Nature that is valuable to humans — air, water, soil, forests, minerals, fuels, sunlight and wind.
  • A part of Nature becomes a resource only when we can use it: it must be technologically accessible, economically feasible, and culturally acceptable.
  • We can sort resources by use — essential for life, for materials, and for energy. One resource (like coal) can fit in more than one group.
  • We can also sort them by whether they refill. Renewable resources (sunlight, wind, forests, river water) refill in our lifetime if we do not over-use them. Non-renewable resources (coal, petroleum, metals) took millions of years to form and cannot be replaced once used up.
  • Nature works in cycles with no waste, and renews herself through restoration and regeneration — but only if we do not take faster than she gives back.
  • Over-using a renewable resource (like pumping groundwater faster than rain refills it, as in Punjab) can make it run out, just like a non-renewable one.
  • Resources are spread unevenly, which shapes settlements, trade and even conflicts; and the resource curse shows that resources alone do not make a country rich — skills and industries do.
  • Stewardship means using resources wisely: restore and regenerate renewables (water harvesting, organic farming as in Sikkim), and use non-renewables judiciously while switching to alternatives (solar power, greener building materials) — so resources last for us and for future generations.

What’s Next

Now you understand how the land beneath our feet — its soil, water, forests and minerals — supports all of human life, and why we must protect it.

In the next chapter, Chapter 2 — Reshaping India’s Political Map, we turn from Nature to people and power. We will see how the political map of India was redrawn over time — how kingdoms rose and fell and borders shifted. Get ready to travel into the story of how our country took shape!

Frequently Asked Questions

What is the difference between renewable and non-renewable resources?

Renewable resources refill themselves in a short time, within our lifetime, as long as we do not use them too fast. Examples are sunlight, wind, forests and river water. Non-renewable resources took millions of years to form and cannot be made again quickly, so once we use them up they are gone. Examples are coal, petroleum and metals like iron and gold.

When does something in Nature become a resource?

A part of Nature becomes a resource only when humans can actually use it. It must pass three tests. It must be technologically accessible (we can reach and extract it), economically feasible (getting it is worth the cost), and culturally acceptable (society allows us to use it). A tree is part of Nature, but it becomes a resource when we cut it and turn the wood into furniture.

Why is Punjab's groundwater running out?

In the 1960s Punjab's farmers switched to high-yielding wheat and paddy that need a lot of water, and free electricity let them pump groundwater heavily. They drew water far faster than the rain could refill it, so the deficit built up year after year. Today about 80 percent of Punjab is classed as over-exploited and water in many areas has dropped below 30 metres deep.

What is the natural resource curse or paradox of plenty?

The natural resource curse means that having a lot of natural resources does not automatically make a country rich. Some resource-rich regions grow slowly because they only sell the raw resource and never build industries to turn it into higher-value products. India has mostly avoided this curse by investing in technology and skills to process its resources.

How did Sikkim become a fully organic state?

Sikkim's government promoted organic farming across the whole state. Farmers like Pema's family stopped using chemical fertilisers and switched to compost and natural pest repellents made from neem and garlic, and grew many crops together. Yields dropped at first while the soil recovered, but after about five years farms thrived. In 2016 Sikkim became a 100 percent organic state, biodiversity returned and farmers' incomes rose.
